END-MATOHER TRIM GAUGE FOR- S AVS.

Application filed August 10, 1926. erial N'o. 128,431.

This invention relates to gauges for end matcher saws, and has for itsobjectto provide a device of thischaracter whereby as pieces ofmaterials, for instance iiooring, are fed towards the saw, said piecesof material are moved longitudinally inwardly to a position where theywill be engaged by the saw relatively close to the ends of the pieces`thereb y reducing the amount of material cut from the flooring' to aminimum and obviatingl waste. y

A further object is to provide a guide bar against which the ends of thepieces of flooring,` slidably engage as they are fed towards the saw,and the guide bar with a' roller which engages the ends of the pieces offlooring adjacentthe saw for movingr said pieccs of 'liooring inwardlytoa position where a minimum amount of cut will be taken therefrom bythe saw. rl`he roller forms a rolling engagement with the end of theboard p whercby said roller will roll out of eng'agenient with the guidethereby obviating` fricionalengagement with the guide during the sawlngoperatlon and preventmg sphtting or shattering of the end of the board'A furthcr object is to provide the guide bar with an inwardl extendmo'anoular a I n b 'tj portlon on wnich the roller 1s mounted, and

which'angular portionengages the ends ofV the boards as they are fedtoxl'ards the saw, thereby moving said boards longitudinally to aposition where they will be engagcdby the saw relatively close to theends of the boards thereby insuring a minimum amount of cut from theends of the board and reducing waste of material to a minimum.

A further obj ect is to provide the angular portion of the guide barwith a bifurcation in which .isrotatablymounted a board engaging roller,and which roller is dislxfsed adjacent the same. `Also to 'provide theedge of the roller of a thickness less than the groove of a boardwhereby it will not jam in the groove of the boardiand cause splittingor shattering of the vopposite sides thereof.

With the above and other objects in view the invention resides in thecombination and arrangement of 'parts i as hereinafter set forth, shownin the drawing, described and claimed, it being1 understood that changesin the precise embodiment of the invention may be made within thescopeof what is claimed .without departing from the spirit of the lnvent'ion.

In the drawings Figure 1 is a top plan view of a Conventional form ofmatching machine showing the gauge applied thereto.

Figure 2 is a side elevat-ion of the gauge.

Figure 3 is a detail plan view of a modified form of gauge showing anadjustable board engaging member carried thereby. j

Figure 4 is a side elevation of the gauge shown in Figure i y Figure 5is a perspective view of the gauge members shown in Fignres 3 and 4.

Referring` to the drawing, the numeral 1 designates the table of asawingI machine, over which table boards 2 are moved by any suitablemechanism and in the direction of the arrow (z, and towards the saw andpresser arms {l'. The boards 2 are preferably tlooring boards which areof various lengths when fed to the machine, and which machine feeds thesame towards the cut oil' sawv 3, and from which machine the boards passto mcchanism which places atongue on one end and a groove on theotherend of the boawfl, therefore it will be seen that it-f will benecessary for the ends of the boards 2 to be square before the tongueand groove operation, and at the same time in the squaring` up operationit necessary for` the minimum amount of material to be cut from theendsfof the boardto obviate wastev which y of bolts 5 is a horizontallydisposed. guide' bar` 6, which guide bar' is in parallel relation to thecut oil' saw 35 and held in spaced relation to the ,table 1 by means of'sleeves T, which sleeves 1nayflbei'varied`in length for varying thedistance of the zqui-de bars 6 from the saw The ends of the boardsf, asthey movel in the directionof the arrow (iu are in' engagement with theinner side of the guide bar 6, and as the boards approach the cut offsaw 3, as they are fed towards said sawa the ends 8 thereof engage theinvardly inclined arm 9, and which arnr) causes the boards 2 to lbemoved longitudi` nally inwardly as they are fed towar-ds the cutoff saw.Rotatably mounted in a bifurcation 10 of the arm 9 is a horizontaliydisposed roiler 10, which rolier is finaliy en' gaged by the end of theboard as it reaehes the saw 3, and which engagement imparts the finalinward movement on the board and positions the end 8 thereof where theminimum amount ofniateriai will. be cut therefrom by the cut-off saw 3during the squaring of the end of the board as elearly shown inFigure 1. rl`he roller 10 has its outer edge 11 relatively thin andpreferably narrower than the width of the grooves 12 in the vboardswhereby said roiier Will not bind or frictionaiiy engage in the grooves12 during the passage of the boards over the roiler, t'hereby preventingspreading' of the walls of the grooves and shatterin;` of said walls..The rolier 10 is rotatably mounted on a vertial1y disposed pin 11:5,which esztendel through the arm 9, and which pin is heid iu position bymeansof set screws 14-. Exteudiiu;v ulnmrdly adjacent the outer eide ofthe guide bar G'i a brucketl, which bracket is connected to the guidebar` Gin any suit' abie manner and adjueted inwardiy and outwardly bymeans ofzan adjustino eerew 16, however the bracket 15 braces the guidebar adjacent the saw and adjacent the inciined portion thereof, therebypreventing' outward inovement or springing of the bar, and at the sametime in eomhinationwith the boits and the removable sieeve 7, allows an`inward and outward adjustment. of thegaugeand guide. Rollers 10. mayvary in thiekness according' to the size of material`` that is passedthrough the device and by providing` the removable pin lrand set screwslet the roliers may be easiiy and quiehiy `changed.

Referring to Figuree'' to inclusive, the construction and operation ofthe modified form is subst'zantiafliy the same usehown in Figuroe 1 and2, with the exeeption the rolhu' is ehnunated, and the arm S) providedwith an extension 17 in parallel reiationto the guide arm G, andextendinp; the/arms S) and. is` a horizontaiiy disposed board eugagingmember 18, whirih board cufan'iiur nieudier ie provided with an end if)iu the .piano of the inner `f-1ide `of the arm i). and

",lfhe board ongagnig member at its order end provided with upwardiy anddownwardlv ext-ondnig arms 20, m which are rotatablv mounted at 21adjusting ecrews 22, and it Will be Seen by adjusting the serewe 22, themember 18 may be adjusted inwardiy and outwardly for aceurateiypoeitioning the outer ends 19 thereof in relation to the saw 3, and tothe arm 9, otherwise the eonetruetion and operation is eubstantiailytheezune as shown in Figures 1 and 2.

From the above it will be seen that guidin- `means is providedcooperating With the ends of boards for :moving the same inwardly aesaid boards are fed towards a cuto'ti' eaw, which saw squares the' endsof the boards, and by moving the boards 1oiugitudinaiiy` inwardly theyare positioned where the minimum amount of material will be envered fromthe ends thereof therebyreducing the waste of material to a minimum.

A set serew ie provided for holding the member 18 in adjuetcd positionafte' au adjuetinent thereof through, the medium of the boite 22. y
